SFECIFICATION forming part of Letters Patent No. 750,907, dated February2, 1904.

Application filed June 10, 1903. Serial No- 160.869- (No model.)

To col-Z whom, it may concern.-

Be it known that I, REFEL STERN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, have Vinvented certain new and useful Improvements in Printing-Presses, ofwhich the following is a specification.

This invention relates to printing-presses, and has particular referenceto the platen type thereof employed for miscellaneous printing.

The objects of the invention are, generally speaking, to provide amachine for printing cards, newspapers, circulars, posters, notices, andthe like continuously upon a paper strip and severing the individualimpressions; to make the several operations automatic and doing awaywith press-feeding by hand and its attendant dangers of bodily injury;to provide a combination of machine elements that are simple as opposedto intricate parts,which may be easily understood and operated by anyoneand which shall not easily get out of order; to expose the work in plainview while in transit that any errors or inaccuracies mayv be promptlynoted, and to make the different parts of the machine readilyaccessible.

The invention consists generally in the combination,with a stationarybed, of a reciprocating type-form having an inking-surface and a type orimpression surface, an inkingroller, and means actuating said platen androller whereby their united movements will cause said roller to passover the surfaces of said type-form.

The invention further consists in a novel impression-plate having aninking-face and a type-face forming a continuous surface with itsseveral faces arranged in different planes.

The invention further consists in the combination, with a rotatingshaft, of a type carrying and type-inking form and roller rocked,oscillated, or reciprocated by pitmen and means upon said shaft foractuating said pitmen.

The invention further consists in a formactuated feeding mechanism and apaper-cutting mechanism actuated by the latter.

The invention further consists in novel means for varying the length ofthe intermittent movements of the paper-feeding mechanism.

The invention further consists in a novel paper-gripping mechanism formoving the paper forward or advancing it from a roll of paper after eachtype impression.

The invention further consists in a paperfeeding and a paper-cuttingmechanism arranged in substantially a direct line and positivelyactuated by pivoted connecting-rods; and the invention further consistsin the novel details of construction and combinations of partshereinafter described in detail, illustrated in the drawings, andpointedout in the claims.

Referring to the accompanying drawings, forming a part of thisspecification, Figure 1 is a side elevation of a printing-pressembodying my invention. Fig. 2 is a top plan View thereof. Fig. 3 is anenlarged side view, partly in section, of the paper-gripping mechanism.Fig. 4 is a plan View thereof. Fig. 5 is a sectional view takensubstantially on the line 4c of Fig. L. Fig. ,6 is an enlarged planView, partly in section, of the driving-slide actuated by the form ortype-carrier. Fig. 7 is a sectional view taken on the line 3/ y of Fig.6; and Fig. 8 is an enlarged perspective view of the form ortype-carrying and inking plate, together with the inking-roller.

. In the drawings, 2 represents the frame of the machine, consisting offour uprights 3, cross-pieces 5, the horizontal extension-rails 6 and 7,and their connecting cross-pieces 8.

9 represents the bed-plate, supported at each of its corners on screws10, held in threaded apertures in the brackets 11, secured to or forminga part of the uprights 3. By means of these supporting-screws thebed-plate may be properly adjusted with relation to the rocking orreciprocating inking and type-carrying plate 12. The latter is pivotedupon bearings 13, held in brackets let, secured to two of the uprights3. At the upper ends of the latter are suitable bearings for the shaft15, to one of which is keyed a knuckle wheel or disk 16. The oppositeend of said shaft carries a gear 17, having a knuckle similar to that ondisk 16. Pivoted to the knuckles of said disk and gear are pitmen 19 and19, which in turn are pivoted to the journals of the inking-roller 21.Between the uprights 3 the shaft 15 is bent into the form of two cranks22 and 23, to each of which is pivoted a pitman 24. Each of the latteris also pivoted to the platen and inking-plate 12 at 25 25. A pin 26upon each of the pitmen 19 19 carries one end of a spiral spring 27,secured at its other end to a suitable pin in the upright 3. The shaft15 is retated by a pinion 28 meshing with the gear 17. Said gear iskeyed to a short shaft 29, having bearings in a bracket 30, bolted, asshown, to one of the uprights 3. The form 12 has an inking-surface 31and a type-surface or impression-face 32 and is bent into the form ofan'angle-plate comprising a type-wing 33 and an inking-table 34. Theportion 33 has an undercut groove 35 in each of its side edges adaptedto slidably hold the head of a bolt 36 for each of said grooves. Anenlarged or widened portion 35 at the upper end of said grooves isprovided for the insertion and removal of the head of the bolt. Theouter or threaded ends of these bolts, one of which (labeled 36) isshown in Fig. 1, are provided with short sleeves (not shown) of largerdiameter than the widths of the apertures or grooves 35. The nuts 37 onthe bolts 36 are tightened against the ends of said sleeves, clampingthe latter against the edges of the grooves 35. Pivoted upon saidsleeves are connecting-rods 38, pivoted to and between bearing-lugs 39upon the slide 40, having slide-bearings in the brackets 41, bolted orotherwise secured to two of the uprights 3. Said slide-bearings comprisethe upper surfaces of the brackets 41 and plates 42, held by screws 43,which are threaded into suitable apertures in said brackets. The inneredges of these plates are rabbeted, as shown by dotted lines in Fig. 6,for the bearing edges 44 of the slide 40. On the outer end of the slideis a knuckle or pivot 45 for the pivoted end 46 of the connecting-rod 47held upon said knuckle by means of a retaining-washer 48 and a screw 49,threaded into the end of the knuckle 45. As shown in Fig. 2, a slide 40,and associated part-s above described, is provided for each side of theframe 2. The other ends of rods 47 are pivoted to the two pairs of lugs50 upon one end of the gripper 51. The latter consists of a frame 52,supported at its opposite edges for a sliding movement between the upperextension-rails 7 of the frame and the tracks or slideways 53.

As clearly shown in Figs. 3 and 4, the gripper-frame 52 carries anotherframe 54, pivoted upon screws 55 within the frame 52. The two framescoact as a pair of tongs which grip the paper at each forward movementand release it on the return stroke. The

mechanism for opening and closing the jaws inner or angularly-movableframe 54. The wheels 56 are caused to travel over and under the tracks59, consisting of metal plates secured by means of screws 60 to blocks61, which may be either integral with the top extension-rails 7 orseparate blocks secured thereto in any suitable manner. Theangularly-movable frame 54 is provided at one end with a weight 62,which tends to tilt up the trolley end of the frame and to cause thetrolleys to mount the tracks 59. To tilt the frame 54 in the oppositedirection or close the jaws, I have provided inclined blocks 63, securedto the under side of the tracks 53 and projecting under the sides of theframe 54. These blocks 63 are arranged in the path of the weight 62, sothat the latter will be lifted thereupon at the moment the trolleys 56are at the end 59' of the tracks 59 and tilt down the trolleys belowsaid tracks. formed by the two frames 52 and 54 upon the strip of papertherebetween, and on the return stroke the trolleys will travel againstthe under side of the tracks 59, carrying the strip of paper along untilthe trolleys reach the end 59", when the weight 62 will tilt them up toagain travel over the upper surfaces of the tracks 59 and simultaneouslyrelease the strip of paper represented by the dotted lines labeled 64and full line 64. The length of the reciprocal stroke of the gripper 51on the tracks 53 is adjustable by means of the bolts 36, adjustable inthe slots 35 of the platen. By moving them downward toward the pivotalend of the platen the ends of the rods 38, pivoted on the platen, willdescribe a shorter arc, and vice versa. Changing the length of stroke inthis manner also necessitates changing the lengths of the track-plates59 correspondingly, which, as previously described, are removably heldupon the blocks 61 by means of screws 60. Other means than screws may ofcourse be provided for holding these plates or tracks-- such as, forinstance, pockets in the sides of the blocks constructed to firmly holdthe edges of the plates. These tracks may also be in the form ofangle-brackets comprising both blocks 61 and tracks 59, mountedremovably upon the top rails 7 in any suitable manner. The end of thegripper 51 which is opposite to the lugs 50 is also provided with asimilar pair of pivot-lugs 65 near each corner of said end. A pair ofrods 66 are each pivoted at one end to these lugs and have their otherends pivoted upon pivot-brackets 67 secured by screws 68 to a cutter 69,slidably held between a pair of bearing-plates 70, secured at each sideof the frame to the upright crosspieces 8, one of which is shown inFig. 1. This cutter 69 being connected to the gripper 51 by means of therods 66 reciprocates with said gripper. A second stationary cutter 71,cooperating with the cutter 69, is secured to a bracket 7 2 by means ofscrews 73, and the end of the paper 64 is fed between said cutters Thisoperates to close the jaws ITO cutter 69.

between guide-rollers 4. Sufficient space is left between these rollersto permit the end of the form of an ordinary roll of paper mounted on ashaft 75, journaled in bearing-brackets '76,

secured by any suitable means to the two outer uprights 3.

The operation of my invention is as follows: The pulley 18 is connectedby means of a suitable belt with a suitable source of power.

W hen said pulley is rotated, the gear 17 will be rotated through thepinion 28, and therewith the shaft 15, which will revolve th'e cranks 22and 23 and the knuckle wheel or disk 16 and knuckle-gear 17. As shown inFig. 1, the throw or crank movement of the knuckles to which rods 19 and19 are pivoted is in the opposite direction to that of the cranks 22 and23, reciprocating rods 24, and as the form 12 moves away from the bed 9the inking-roller 21 will be moved toward the bed over the inking tableor surface 31 and the type-face 32, the springs 27 keeping the inkingroller against the latter face as it passes over the angle formed by thetwo faces presented to it by the surface 31 and type-face 32. As theform moves or oscillates back toward the bed 9 the roller 21 is carriedback upon the inking-surface 31, the combined movements of roller andform in opposite direction giving the roller with reference to thesurfaces 31 and 32 a movement corresponding to the combined reciprocalstrokes of the cranks 22 and 23 and the knuckles on disk 16 and gear 17as to the length thereof.

Referring now to the paper-feed and papercutting mechanism actuated bythe platen, starting from the position of the form shown in Fig. 1, asthe platen moves downward, or toward the bed 9, the rods 38 will movethe slide 40 outwardly away from the bed, and said slide will carry withit the gripper 51. At the moment the form is parallel with the bed ormakes its type-impression upon the paper 64 upon said bed the trolleysupon the gripper will have reached the end 59 of the tracks 59 and dropdown below said tracks through the action of the inclines 63 cooperatingwith the weight 62, previously described.

Simultaneously therewith the cutter 69 will have been moved forwardagainst the cutter 71 and cut off the end of the paper therebetween. Onits upward or return movement away from the bed 9 the form will pull the64 represents the paper-supply in I slide 40 toward the bed, which inturn will push the gripper 51, between which the paper is now held, inthe direction of the cutters, and the latter being separated the end ofthe paper fed forward will be permitted to drop down between thecutters.- Having completed its upward reciprocal movement, the form willhave forced the trolleys :to theend 69 of the tracks 59, when the paperwillbe released by the trolleys tipping-to the upper surface of saidtracks and opening the jaws formed by the two frames 52'and 54:, and soon.

hile I have illustrated the bed and paperfeed mechanism as occupying ahorizontal position, itis obvious that same may be placed vertically bysimply changing the direction of motion of the cutters at right anglesto the plane of the paper, in which event the guiderollers 74 may bedispensed with. 'In the latter arrangement the springs 27 might also bedispensed with and the force of gravity alone depended upon to hold theinking roller against the inking and type surfaces of the form. Themechanism for moving the paper forwarchstep by step may also be modifiedin numerous waysas, for instance, a pair of feed-rollers at each edge ofthe strip of paper actuated by the slide 40 to rotate only in onedirection, as previously referred to in connection with the rollers 74,and in numerous other ways and while for the purpose of clearlyillustrating my invention I have shown a comparatively large frame theparts may be arranged much more compactly.

As numerous modifications may be made in the details of structureembodying my invention by one skilled in the art, I do not confine myinvention to the specific construction herein shown and described.
